Abstract

Flower-like Bi2WO6 microspheres were prepared by a facile hydrothermal method, and AgCl/Bi2WO6 heterojunction was successfully synthesized by in-situ precipitation method. The samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and UV-vis diffuse reflectance spectroscopy (DRS). The effect of AgCl loading in AgCl/Bi2WO6 composites on the degradation of Rhodamine B (RhB) was also investigated. When the mass ratio of AgCl to Bi2WO6 was 4:1, AgCl/Bi2WO6 composites exhibited the highest photocatalytic degradation efficiency of 87.9% within 30 min, which could be attributed to the construction of heterojunction structure that effectively promoted the separation of photogenerated electron-hole pairs.
